Abstract
Kejadian keterlambatan dalam penyelesaian proyek memiliki dampak yang luas dan merugikan diantaranya denda keterlambatan, buruknya reputasi kontraktor bahkan dampak kerugian bisnis bagi project owner. Sebagai upaya dalam menghindari dampak negatif dari kejadian keterlambatan, maka perusahaan konstruksi wajib melakukan upaya perbaikan agar perusahaan terus mampu bersaing dalam pasar yang semakin dinamis dan kompetitif, ditambah dengan kondisi krisis finansial dan resesi ekonomi seperti saat ini menuntut perusahaan untuk melakukan efisiensi serta peningkatan efektifitas kinerja melalui terobosan dan metode improvement. Penerapan metode lean, six sigma atau kombinasi keduanya dapat menjadi sebuah solusi karena metode ini adalah sebuah terobosan kajian manajemen yang berfokus pada upaya peningkatan efektifitas kinerja dan efisiensi proses. Konsep popular ini lahir sebagai metode revolusi manajemen industri manufaktur menghasilkan cerita kesuksesan perusahaan ternama dunia. Perkembangan penerapan motode ini mulai juga banyak digunakan pada manajemen proyek konstruksi dimana diharapkan membawa keberhasilan yang sama seperti pada penerapan di industri manufaktur. Dalam penelitian ini metode lean six sigma (LSS) digunakan sebagai perbaikan paradigma dan alat analisis pelaksanaan proyek obyek study dimana ditemukan terjadi keterlambatan dalam penyelesaian pekerjaan. Input dari penelitian ini adalah berupa data faktor keterlambatan serta waste yang terjadi pada proyek melalui penyebaran kuesioner kepada stakeholder utama dalam proyek. Selain itu untuk melengkapi analisis pengukuran kinerja digunakan juga data sekunder dari data laporan kemajuan pekerjaan dan penggunaan biaya proyek. Penelitian ini akan menghasilkan output dari metode lean berupa critical waste dimana diduga menjadi penyebab dominan dari keterlambatan proyek obyek study yang kemudian dilakukan analisis menggunakan root cause analysis dan if then recommendation. Analisis usulan improvement lainya dilakukan dengan peninjauan pada value stream proses yang diharapkan mampu meminimalisir Non Value Added Activity. Output metode six sigma adalah berupa indikator kinerja LSS-PI dimana ditemukan pada pengukuran kinerja proyek existing menunjukkan nilai SPI dan CPI bernilai negatif artinya kinerja proyek buruk secara biaya dan penjadwalan, kemudian digunakan juga dalam penetapan nilai ambang batas sebagai alat kontrol kinerja perbaikan kualitas kedepannya dari sudut pandang ketepatan waktu, biaya, mutu, efektifitas proses serta pemborosan inventory.
=========================================================
The incidence of delays in completing project activities has a very detrimental impact, including late penalties, a decrease in the contractor’s reputation and even the impact of business opportunity losses as a project owner. As an effort to avoid the negative impact of delays, construction companies are required to make improvements so that the company is able to compete in an increasingly dynamic and competitive market, this is also emphasized by the current financial crisis and economic recession, which requires companies to introspect, make efficiency and increase performance effectiveness through breakthroughs improvement methods. The application of lean methods, six sigma or a combination thereof, can be a solution because this method is a breakthrough management study that focuses on efforts to improve performance effectiveness and improve process efficiency. This popular concept emerged as a revolutionary manufacturing industrial management method resulting in the success stories of major companies in the world. The development of this method has also begun to be widely used in construction project management which is expected to bring the same success as its application in the manufacturing industry. In this study the lean six sigma (LSS) method was used as a paradigm refinement and an analysis tool for the implementation of the study project where delays were found in the completion of work. The input of this research is data on factors of delays and waste that occur in the project through distributing questionnaires to stakeholders involved in the project. In addition, to complement the performance measurement analysis, secondary data from the work implementation report is also used, including the progress of work and the use of costs. This research will produce the output of the lean method in the form of critical waste which is thought to be the dominant cause of delays in the Camplong salt factory construction project, which is then analyzed using root cause analysis and if then recommendation. Analysis of other proposed improvements is carried out by reviewing the value stream process which is expected to be able to minimize non-value added activity. The output of the six sigma method is in the form of an LSS-PI performance indicator which will be used to measure the performance of existing projects and the determination of threshold values as a means of controlling the performance of future performance quality improvements from the point of view of timeliness, cost, quality, process effectiveness and inventory waste
